Patent GB-1232310-A (GB)
IPC: C01C3/20

Abstract: 1,232,310. Production of aqueous solutions of thiocyanates. GLANZSTOFF A.G. 1 Oct., 1968 [21 Oct., 1967 (3)], No. 46488/68. Heading C1A. Aqueous ammonium thiocyanate solutions are obtained by the reaction of ammonia and carbon disulphide in the presence of water, the reaction being carried out on active carbon at elevated temperature. The process is suitably effected in a reaction tube filled with granulated active carbon, a temperature of 60-100‹ C. being maintained in the reaction zone. In one mode of operation, ammonia and carbon disulphide in a molar ratio from 2:1À2 to 2: 2 are introduced between one quarter and one half the way up the reaction tube filled with granulated active carbon which is mounted on a distillation vessel, and simultaneously steam is supplied from the bottom of the reaction tube from a distillation vessel, the control of the heat supply to the distillation vessel being so effected that the major part of the steam condenses below the point at which ammonia and carbon disulphide are fed to the reaction tube, and the ammonium thiocyanate formed is drawn off at the bottom end of the reaction tube and hydrogen sulphide as well as excess carbon disulphide are drawn off from the top of the reaction tube. The ammonium thiocyanate may alternatively be converted to aqueous alkali or alkaline earth metal thiocyanates by providing an aqueous alkali or alkaline earth metal hydroxide solution in the reaction tube between the points of entry of the steam and the ammonia and carbon disulphide for reaction with the ammonium thiocyanate passing therethrough.

Abstract: 1,257,147. Dyeing pile fabric. E. KUSTERS [trading as EDUARD KUSTERS MASCHINENFABR1K]. 17 Aug., 1970 [16 Aug., 1969; 17 Dec., 1969], No. 39513/70. Heading D1L An advancing pile fabric is dyed by applying dye liquor to the pile surface, followed by contacting the back surface with one or more triturating elements. As described, the dye applicator 2 comprises a trough 10 in which a roller 11, partially immersed, rotates. An inclined plate 12 scrapes the non-immersed part and dye liquor removed from the roller flows onto the pile 1 of the fabric. The fabric subsequently passes through a spiral steamer 4 over groups of rollers which contact the back of the fabric and have a peripheral speed different to that of the fabric, e.g. by rotating faster than or counter to the fabric movement. There may also be provided stationary 19 or moving 18 rods or bars arranged to triturate the back of the fabric. The groups of rollers may have increasing diameters in the direction of fabric travel and have a common drive (Fig. 1). The applicator may be inside or outside the steam chamber.

Abstract: 1,265,671. Extruding. R. CHADWICK, and O. E. FLETCHER. 2 Feb., 1970 [15 Feb., 1969], No. 8325/69. Heading B3P. [Also in Division G3] In a process of hot extrusion of metals, e.g. aluminium alloy, the speed at which the metal billet 14 is forced through a die 16 by an hydraulic ram 10 is varied in order to ensure that the extruded metal emerges from the die at a constant predetermined optimum temperature, the friction between the die and metal billet inducing heat particularly in the extruded metal which is likely to be at a higher temperature than the rest of the billet. There is a maximum temperature, e.g. 460‹ C. above which the quality of the metal is affected (e.g. grain coarsening, surface cracking). The billet is preferably pre-heated before extrusion, e.g. to 440‹ C. Allowing for loss in heat before extrusion of say 20‹ C. then the permissable max. generated heat would be 40‹ C. The extruded metal temperature is sensed continuously by a radiation pyrometer 28 the initial reading of which is corrected by comparison with a more accurate temperature recorded by a contact pyrometer 23. Pyrometer 23 has sensing prods (e.g. thermocouples) which become embedded in the leading end portion of the extruded metal and tend to damage the metal, the affected portion of which has to be discarded. The contact pyrometer is therefore used for initial calibration only or may be used intermittently during the extrusion cycle and is mounted on a carriage 20 for movement along the direction of the extrusion and at right angles thereto. The corrected temperature value is compared with a predetermined value which may be the permissible maximum and the difference value is used to automatically control the hydraulic fluid supply to the hydraulic press. Alternatively the fluid supply may be varied manually to adjust the extrusion speed until the difference is zero. The extruded metal may be cooled in a.water bath or spray after it emerges from the die.

Hot and cold water pressure regulated by devices 16, 18 are supplied via a temperature responsive mixing valve 14 to a line 24 having a temperature sensing probe 32. A device comprising a diaphragm 42, a plunger 40, a line 44 and a needle valve 38 controls the flow of warm water to a pump 54 via a flow meter 50. Dialysate concentrate is supplied from a vessel 60 via a pump 62, which maintains circulation of the concentrate in line 66, to the pump 54 which has a venturi nozzle 53 and serves to mix the warm water and concentrate to form dialysate. The pressure of the concentrate supplied to conduit 70 is controlled by the maintenance of a fixed head or the application of gaseous pressure to the surface of the concentrate in vessel 60, Fig. 3 (not shown). Dialysate flows to a solenoid valve 80 from which it passes to an artificial kidney 91 or a drain 94 depending upon the concentration of dialysate detected by a conductivity cell 82. A solenoid valve 99 and a venturi pump 100 enable suction to be applied to the artificial kidney 91 to increase the flow of dialysate. A circuit, Fig. 2 (not shown), for control of the apparatus is also described.
